The Zenin Clan originated from Taira no Masakado. It was said that Taira no Masakado had a son named Taira no Masakuni, and that Taira no Masakuni was the original name of Abe no Seimei. The relationship between Shikigami and Abe no Seimei was well known, and Ten Shadows Technique also carried traces of Abe no Seimei.
As for Kamo Clan, its origin lay with Emperor Sutoku.
In his later years, Emperor Sutoku was exiled by Emperor Go-Shirakawa. To prove his sincerity, he copied five sutras in his own blood, but Emperor Go-Shirakawa regarded them as curses and refused to accept them.
Enraged, Emperor Sutoku bit through his own tongue and wrote in blood on the returned sutras, vowing to become a great demon king and bring chaos to the world, dedicating the five Mahayana sutras to the evil path. He neither ate nor rested after that, and died in fury, his death resembling a yaksha.
It was said that after Emperor Sutoku died, even after the coffin was sealed, blood kept seeping out for a long time. From that blood came the signature technique of the Kamo Clan, Blood Manipulation, using blood itself as the medium.
Akira did not doubt Satoru Gojo's judgment, nor did he feel discouraged. He still wore a calm expression, as if everything were under control.
"It is fine, there are still solutions," he said. "We can use terrain and tools, like building a cage strong enough to trap Shikigami inside, then slowly attack it from outside. There are also modern machines, excavators, Road Roller, anything that can conduct Cursed Energy. Even if it were something like Cthulhu, I would load it onto a ship and take it away."
"Of course, these are external aids," he continued. "They can be borrowed, but never relied on. The key of a technique is always the caster. No subjugation ritual can restrict the caster themselves."
"Do you understand now," he asked, "why I made you train close combat, tool usage, and coordination with Shikigami?"
Megumi Fushiguro's pupils shrank. "The caster should not be limited by the technique. The caster controls the technique."
"Bingo," Akira said. "You never only have Shikigami. Do not let Ten Shadows Technique box you in. Like I said, techniques are dead, people are alive."
As he spoke, he glanced quietly at Satoru Gojo. This was someone who had innovated on an almost perfect inherited technique, pushing himself from strongest toward unbeatable.
It was a pity that Satoru Gojo had done it himself, but never passed that idea on to others.
Given his personality, he probably never realized how important that insight was.
That was the gap between geniuses and ordinary people. Geniuses grasp everything by instinct, while ordinary people have to summarize, correct, and refine step by step just to catch up.
Akira was glad that what he possessed was a "Pokémon Trainer" System. Starting from an egg, starting from zero, allowed him to observe everything clearly and take on the role of an assistant teacher, opening new doors for others again and again.
From that day on, Megumi Fushiguro was no longer the delinquent Megumi Fushiguro. He was simply a junior student of Tokyo Jujutsu High.
"I understand," Megumi Fushiguro said seriously. "Please guide me from now on, Senior Akira, and the other seniors as well. I will do my best to master all shadow techniques, and when that day comes…"
"Bring it on," Maki Zenin said, curling her finger.
"Count me in too," Panda said, raising a paw.
"Salmon," Inumaki replied, continuing his usual speech.
Akira looked at the scene in front of him, a smile forming at the corner of his mouth.
Jujutsu Kaisen wore the label of youthful passion, but in truth it walked a darker path more often than a brighter one, with death and injury as common occurrences. With his help pushing them forward, their future development should be much better.
He only wondered whether, with Megumi Fushiguro growing stronger, Yuji Itadori would still be able to swallow Sukuna's finger and become the spark that started everything.
Still, that might not be a bad thing. Someone as kind as Yuji Itadori was better suited to live in the sunlight rather than the shadows.
As for the villains, Akira could take his time and deal with them one by one.
He really hated that dark path. The brighter side was much better.
"We all have to become strong, and then do something for this world," Akira murmured to himself.
It was at that moment that Satoru Gojo admitted it. "You are more suited to being a teacher than I am. I cannot teach students as well as you can."
"After this, I will be counting on you," he added. "The first years, and Megumi. In a couple of days, there might be another transfer student. If you need anything, just tell me."
"For now, I do not need anything," Akira replied. "I have already received my payment."
There were emotional rewards, like the sincere respect from the boys and girls, and his mother's calm daily life and peaceful smile.
There were also material ones. Salary and royalties were secondary, but the most important was the new prompt from System.
Detection of Trainer meme complete. Meme collection and conversion in progress. New Trainer template added, Green.
No wonder he was the second male lead, with that spiky hair. What even was a cheating player?
It was a routine morning, followed by routine morning training. That was usually followed by routine sparring, and just as routinely the area was cleared by Gardevoir.
There was no helping it. Close combat made blood run hot very easily, and that was when Gardevoir had to step in and forcefully control the situation with Psychic Power, making everyone calm down.
At times like this, Pancham became especially excited. This little troublemaker thrived on chaos, the kind that would start tearing tiles off the roof if left unchecked for three days.
The problem was that the little one had learned to be clever. The moment Akira glared, it would dive straight into Akira's arms, leaving Akira unable to grab it back to spank it or flick its forehead.
He looked away to get some peace of mind and picked a random topic. "The transfer student comes today, right?"
"Probably," Panda nodded. "I heard he stuffed four classmates into lockers."
"Did he kill them?" Maki Zenin asked bluntly.
"No, I think they were just badly hurt."
"Oh. If she is too arrogant, then we will teach her a lesson."
"Bonito Flakes." Cursed Speech. No, compared to the delinquent Maki Zenin, he was far kinder.
"Do not do that, little Maki Zenin," Akira said gently. "I have seen that child before. He is a good kid."
"A good kid?"
Maki Zenin glanced at Akira, then at herself. All of these were considered good kids in Akira's eyes, which somehow made the standard feel very unreliable.
At Tokyo Jujutsu High, aside from Gardevoir, only Toge Inumaki barely fit the idea of a good kid. As for the others, who practiced low blows and thought every day about how to kill enemies, were those really good kids?
"Good or bad, we will see him anyway," Akira said as he sprang up from the ground. "Just to be safe, let me ask. Mom, you are not the one going to pick him up, right?"
"No. Enrollment has always been handled by Gojo-sensei," Akira shook her head.
